AWNING. 5

Application filed January 30, 1923, Serial No. 615,954. Renewed January 18, 1924.

To all whom it may concern.

Be it known that I, WILLIAM E. Mmzcnn, a citizen of the United States of Jtmerica, residing at Rutland, in the county of Butland and State of Vermont, have invented certain new and useful Improvements in Awnings, of which the following is a specification.

My present invention relates to rollertype awnings, and particularly to the method of attaching the awning sheet to the roller; the object of this invention being to provide a simple, effective, and inexpensive means whereby the edge of the awning sheet may be easily and securely attached to the usual roller.

The manner in which I accomplish my object is illustrated in the accompanying drawings, in which:

Fig. 1 is a plan view of a portion of an awning roller with an awning sheet attached thereto.

Fig. 2 is a section across the roller and one of the attaching clamps.

The same reference characters refer to the same parts throughout the views.

All roller-type awnings have an awnin sheet of some suitable fabric, one edge 0 which is attached to a beam or roller around which the sheet is to be wound, means being provided whereby the beam may be rotated at will. In the shorter length roll-type awnings the beam may be of wood, but in the longer awnings of this type it is necessary to use metal tubes in order to secure the desired stiffness of the beam without an unduly large diameter.

Various modes of fastening the awning sheet to the roller or beam have been used. In the shorter length awnings where a wooden beam or roller of allowable diameter proves of sulficient stiffness, it is a simple matter to fasten the awning sheet thereto by nailing through the edge of the sheet into the beam. With wood rollers this method is inexpensive and proves satisfactory.

In awnings of greater length, in which it is necessary to use a metal roller, this method is not feasible; if screws are substituted for the nails, the cost of drilling and tapping the required number of holes makes the cost excessive. It also makes necessary the forming of screw holes along the edge of the sheet.

In fastening the awning sheet to a metal roller the present general practice is to form a series of eyelets along the edge of the sheet which is to be attached to' the roller, and then sew it to the roller by threading a rope through the eyelets. each stitch the portion of the rope between adjacent eyelets) passing one or more times around the roller. An adhesive is sometimes used to assist in fastening the edge of the awning sheet to the roller and to prevent slipping. Usually friction only is depended on to prevent slipping, the necessary amount of friction being obtained by making the awning sheet wide enough so that when the awning is in full extended position one full turn will still be wound upon the roller.

Referring to the drawings, which illustrate my improved awning structure, A, represents a beam or roller of metal. represents the awning sheet the edge thereof which is to be fastened to the roller being folded and stitched so as to provide plural thickness at 12 and this plural thickness is then folded back upon itself and stitched so as to form a band or bead 6 adapted to be engaged by the hook edge 0, of the curved clamping plate C. A screw D, passes through the plate C, and enters a threaded hole formed in the roller A, and when tightened will force the clamping plate strongly against or toward the roller; and when the beaded edge of the awning sheet is in place between the roller and the clamp, the same will be firmly clamped in place. The hook edge a, of the clamp, engaging the front edge of the band or bead b, will aid in preventing the edge of the sheet being drawn out from in under the clamp.

A series of short clamps may be employed, or a long clamping strip. And instead of forming a bead by folding the edge of the sheet, I may form a narrow hem open at both ends and thread therethrough a length of rope.

In attaching the awning sheet to the roller it is desirable that there be no abrupt protuberances over or against which the awning sheet must lie when wound up. I therefore make the clamps C, of sheet metal and form therein a depression adapted to receive the head of the screw D, which fastens the clamp in place, so that when the awning sheet is drawing against the clamps, as it will when not fully unrolled, the draft will be distributed over virtually the whole length of the clamp and not be excessive at the point covering the screw head.

My attaching means provides a simple, effective, and inexpensive means for securely attaching the awning sheet to the roller. The forming of a head at the edge of the sheet is less expensive than the usual eyelets or grommets, and as my plan makes possible a saving in the material necessary for the awning sheet due to the feasibility of omitting the turn about the roller when the awning is fully extended, a further saving in manufacturing cost is possible.

I claim:

1.111 an awning, an awning sheet one edge thereof folded and stitched to form a band of greatly increased thickness along said edge; a roller with a longitudinal row of threaded holes therein; a series of curved clamping plates with a depression in the central part thereof and a hole therethrough, the front edge of said plates bent to form a hook adapted to engage the front edge of said thickened band; and screws passing through said plates and engaging in said threaded holes.

2. In an awning, an awning sheet with a band of increased thickness along one edge thereof; a roller with a row of threaded holes therein; a curved clamping plate with screw holes therethrough, the front edge thereof bent and hooked over band; and screws engaging in said threaded holes and adapted to force said clamping plate into intimate contact with said roller, and the thickened edge of said sheet when interposed between said roller and said clamping plate.

In testimony whereof I have affixed my signature.

WILLIAM E. METZGER.
